Other Contributions NATURE NOTES Amphibia: Caudata Ambystoma ordinarium. Predation by a Black-necked Gartersnake (Thamnophis cyrtopsis). The Michoacán Stream Salamander (Ambystoma ordinarium) is a facultatively paedomorphic ambystomatid species. Paedomorphic adults and larvae are found in montane streams, while metamorphic adults are terrestrial, remaining near natal streams (Ruiz-Martínez et al., 2014). Streams inhabited by this species are immersed in pine, pine-oak, and fir for- ests in the central part of the Trans-Mexican Volcanic Belt (Luna-Vega et al., 2007). All known localities where A. ordinarium has been recorded are situated between the vicinity of Lake Patzcuaro in the north-central portion of the state of Michoacan and Tianguistenco in the western part of the state of México (Ruiz-Martínez et al., 2014). This species is considered Endangered by the IUCN (IUCN, 2015), is protected by the government of Mexico, under the category Pr (special protection) (AmphibiaWeb; accessed 1April 2016), and Wilson et al. (2013) scored it at the upper end of the medium vulnerability level. Data available on the life history and biology of A. ordinarium is restricted to the species description (Taylor, 1940), distribution (Shaffer, 1984; Anderson and Worthington, 1971), diet composition (Alvarado-Díaz et al., 2002), phylogeny (Weisrock et al., 2006) and the effect of habitat quality on diet diversity (Ruiz-Martínez et al., 2014). We did not find predation records on this species in the literature, and in this note we present information on a predation attack on an adult neotenic A. ordinarium by a Thamnophis cyrtopsis. On 13 July 2010 at 1300 h, while conducting an ecological study of A. -

A New Cascade Frog of the Subgenus Odorrana from Peninsular Malaysia

Rana monjerai, new species is a medium-sized frog of the subgenus Odorrana (SVL of males, 38–43 mm; of one female, 75 mm), and is distinguished from all other members of this subgenus by the combination of: white lip stripe, dorsolateral fold, full web on the fourth toe, vomerine teeth, gular vocal pouch and relatively large tympanum in males, no dorsal marking, no clear light spots on rear of thigh, first finger subequal to second, finely tuberculated dorsum, and unpigmented ova. The significance of finding this species from peninsular Malaysia is discussed.

Squamate Reptiles Challenge Paradigms of Genomic Repeat Element Evolution Set by Birds and Mammals
ARTICLE DOI: 10.1038/s41467-018-05279-1 OPEN Squamate reptiles challenge paradigms of genomic repeat element evolution set by birds and mammals Giulia I.M. Pasquesi1, Richard H. Adams1, Daren C. Card 1, Drew R. Schield1, Andrew B. Corbin1, Blair W. Perry1, Jacobo Reyes-Velasco1,2, Robert P. Ruggiero2, Michael W. Vandewege3, Jonathan A. Shortt4 & Todd A. Castoe1 1234567890():,; Broad paradigms of vertebrate genomic repeat element evolution have been largely shaped by analyses of mammalian and avian genomes. Here, based on analyses of genomes sequenced from over 60 squamate reptiles (lizards and snakes), we show that patterns of genomic repeat landscape evolution in squamates challenge such paradigms. Despite low variance in genome size, squamate genomes exhibit surprisingly high variation among spe- cies in abundance (ca. 25–73% of the genome) and composition of identifiable repeat ele- ments. We also demonstrate that snake genomes have experienced microsatellite seeding by transposable elements at a scale unparalleled among eukaryotes, leading to some snake genomes containing the highest microsatellite content of any known eukaryote. Our analyses of transposable element evolution across squamates also suggest that lineage-specific var- iation in mechanisms of transposable element activity and silencing, rather than variation in species-specific demography, may play a dominant role in driving variation in repeat element landscapes across squamate phylogeny. 1 Department of Biology, University of Texas at Arlington, 501S.

Advice to the Minister for Sustainability, Environment, Water, Population
The Minister included this species in the vulnerable category, effective from 11 May 2012 Advice to the Minister for Sustainability, Environment, Water, Population and Communities from the Threatened Species Scientific Committee (the Committee) on Amendment to the list of Threatened Species under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) 1. Name Acanthophis hawkei The species is commonly known as the plains death adder. It is in the Family Elapidae. 2. Reason for Conservation Assessment by the Committee This advice follows assessment of information provided by a public nomination to list the plains death adder. The nominator suggested listing in the vulnerable category of the list. This is the Committee’s first consideration of the species under the EPBC Act. 3. Summary of Conclusion The Committee judges that the species has been demonstrated to have met sufficient elements of Criterion 1 to make it eligible for listing as vulnerable. 4. Taxonomy The plains death adder is conventionally accepted as a distinct species. The species has been formally described by Wells and Wellington (1985) and the subsequent genetic work by Wüster et al. (2005) allows the species to be defined by reference to a phylogenetic clade and accessioned sequences. A scientific institution has a specimen of the species (Northern Territory museum (R3677)) and the taxon is recognised as a distinct species by both the Northern Territory museum and the Queensland Museum. 5. Description The plains death adder is a robust terrestrial snake which grows to a maximum length of approximately 1.2 m (Wells and Wellington, 1985). The species’ dorsal side ranges in colour from shades of grey to a brownish-red, usually with wide, lighter bands across the body. -
Dendrelaphis Pictus (GMELIN, 1789) Complex – 2

Mehrere phänetisch unterschiedliche Cluster sind erkennbar. Geografisch werden diese Cluster durch wichtige biogeographische Barrieren wie zum Beispiel der Isthmus von Kra, die Wallace Linie und die Weber Linie getrennt. Die indochinesischen und die Sunda-Populationen werden trotz morphologischer Unterschiede zwischen ihnen unter dem Namen D. pictus zusammengefaßt, da sie als nicht voneinander unabhängig betrachtet werden. Zwei weitere Cluster werden als eigenständige Arten betrachtet, da diese Populationen ohne Zweifel unabhängige evolutionäre Linien bilden. Der erste dieser Cluster umfaßt die Populationen der Philippinen und Sulawesis. Diese Populationen werden unter dem Namen D. marenae beschrieben. Diese Art unterscheidet sich von den bisher benannten Formen in der Färbung, der Größe der Vertebralschuppen, der Anzahl der Subcaudalia und der Schwanzlänge. Der zweite Cluster umfaßt die Populationen der Molukken, welche mit dem Namen D. grismeri belegt werden. Diese Art zeichnet sich durch die Anzahl der Ventralia, Subcaudalia und Temporalia sowie die Schwanzlänge aus. ABSTRACT The Southeast Asian, Indonesian and Philippine forms of the polytypic Dendrelaphis pictus (GMELIN, 1789) are reviewed using multivariate analyses. Several distinct phenetic clusters are discerned. Geographically, these clusters are separated by important biogeographic boundaries, such as the Isthmus of Kra, Wallace’s line and Weber’s line. -
